Emergency Light Sensor and LED Illuminator

This project is a modification of Utsource's project, "RGB LED Interfacing with Arduino." The original project was supposed to demonstrate how RGB LED can be used with an Arduino interface. The purpose of this device is to illuminate the direction of the exit during an emergency when lights are out. With this modification, we can further demonstrate the applications of the RGB LED.

This modification includes an extra part - the light-dependent resistor. The light-dependent resistor and the new code will enable the device to detect the luminosity of the environment and change the light intensity by reducing resistance.

Preparing the Parts
